A new compound K_6FeNb_(15)O_(42) was prepared for the first time by solid state reaction in K_2O Fe_2O_3-Nb_2O_5 ternary system. The X-ray powder diffraction d
The coadsorption of cyclohexanone and oxygen on Pt(111) has been investigated by HREELS and TDS. At 205 K the presence of oxygen induces an “extra” red|shift
